Sql Browser not returning all sql instances on a machine

I have 2 instances of Sql Server on my pc:

A named instance of Sql Express (\SQLEXPRESS)

And a default instance of Sql Developer edition.

Using SSMS, when I browse for servers on my machine, I only get the Sql Express instance listed as being available on my machine.

I know that I have the server itself configured and accessible because if I type the connection string manually, I can connect to it via Sql Authentication and Windows Authentication both locally and from other machines. And I know the Sql Browser is at least returning some information as the Sql Express instance is browsable.

After some googling for a solution, the closest information I can find to my problem is this MSDN Article. However, as far as I know, I haven't chan开发者_开发百科ged the name of my computer since the OS was installed (Win 7 x64) let alone since Sql was installed.

Any ideas about why the browser doesn't recognise the other instance greatly appreciated.

Thanks Andy

if the HideInstance Flag is No for both the instances and still not showing check out these 2 Posts in SO and DBA.Stackexchange

and try this registry Key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\90\SQL Browser\SsrpListener

make sure it has value 1 if you cant find it under 90 folder, search for SsrpListener because if you read the background section of SQL Browser service , you see that browser service was originally SQL Server Resolution Protocol (SSRP)
